PUB1, targeting protein that aids in RNA translation and export
Polyuridylate-binding protein (PUB1) is a member of the ribonuclear protein consensus sequence family of RNA-binding proteins and is structurally related to the human heterologous nuclear RNA-binding proteins (hnRNP) M proteins. PUB1 is localized in a non-uniform pattern throughout both the nucleus and cytoplasm. Antibodies were raised against a preparation of yeast proteins UV crosslinked to polyadenylated RNA.

PUB 2, targeting protein that aids in RNA translation and export
Polyuridylate-binding protein (PUB2) is also a member of the ribonuclear protein consensus sequence family of RNA-binding proteins and is structurally related to the human heterologous nuclear RNA-binding proteins (hnRNP) M proteins. PUB2 has partially overlapping function with Pub1. Antibodies were raised against a preparation of yeast proteins UV crosslinked to polyadenylated RNA.

Pab1p, targeting protein involved in the construction of mRNA molecules
Pab1p is a protein which binds poly-A tails of yeast mRNA molecules, and is known as polyA binding protein. It is also known as PAB1, ACBP, CST11 and MRNP and the systematic name is YER165w. It is the only yeast poly-A binding protein, and is found in both the cytoplasm and nucleus of yeast cells. The protein has a molecular weight of 64kDa and antibodies were raised against a preparation of yeast proteins UV crosslinked to polyadenylated RNA.

Nab1p, targeting a DNA binding protein in yeast
Mammalian protein arginine methyltransferase (PRMT1) is related to a protein arginine methyltransferase (RMT1) in yeast. This same yeast gene has been independently isolated as an hnRNP (heterogeneous nuclear ribonucleoprotein particle) methyltransferase (HMT1). The substrate specificity of recombinant Rmt1p/Hmt1p indicates that this enzyme is a protein methyltransferase I that methylates glycine/arginine-rich domains. Nab1p is one of the “heterogeneous nuclear RNA” or hnRNA binding proteins of yeast. Nab1p is also sometimes referred to as Npl3p, MTR13p, MTS1p and NOP3p and the systematic name is YDR432W. Nab1p is localized in the nucleus where it has a reticuled expression quite different from, for example Nop1p/fibrillarin. The antibody was raised against a preparation of yeast proteins UV crosslinked to polyadenylated RNA.

Nab2p, targeting an RNA binding protein that regulates mRNA within cells
Nab2p is a nuclear polyadenylated RNA-binding protein which autoregulates mRNA levels. It is related to human hnRNPs and has nuclear localization signal sequence that binds to Kap104p; required for poly(A) tail length control and nuclear mRNA export.

Nab3p, targeting a DNA binding protein that regulates production of mRNA
Nab3p is a single-stranded DNA binding protein (also known as Hmd1p); acidic ribonucleoprotein; required for termination of non-poly(A) transcripts and efficient splicing; interacts with Nrd1p. The antibody was raised against recombinant Nab3p-maltose binding protein fusion protein.

Nab4p, targeting protein that binds RNA for gene expression
Nab4p is a nuclear polyadenylated RNA-binding protein also known as Hrp1p. It is a subunit of cleavage factor I, a five-subunit complex required for the cleavage and polyadenylation of pre-mRNA 3' ends. The antibody was raised against a Nab4p-GST fusion protein.
